I wanted to get a few opinions on the best way to prep a block for filler (Hard Blok). In the past I have hot tanked the block, pressure washed it and then used muriatic acid for the final cleaning. Drained the acid, pressure washed again, dried and poured. I don't like working with muriatic and haven't used it for years, but am concerned I won't get it as clean as it should be. Any comments or alternate ideas?
